Well, I would assume that's a temporary error. The Linux server and IIS probably have different IPs, so it will take a few hours to a couple days for everyone's DNS records to be updated. I can recommend something to see if it will work, but it all depends on how computer literate you are. You can try changing your DNS settings for your computer to use your hosting company's servers. Since their servers are updated with the change to your site immediately, if I'm right when you do this you should be able to see the site fine. The DNS server for them appears to be 213.171.218.193.
I'd try it for you, but I'm at work and we can't change our DNS settings.
